Friedr. Dick Premier WORLDCHEFS is the unique composition of a hygienic non-sticking coating and a precious mother of pearl handle. The high quality coating resists materials sticking to the blade and facititates cleaning. Both Friedr. Dick and the World Association of Chefs Societies (WORLDCHEFS) endorse this product. This knife series has been developed in cooperation with F. Dick and WORLDCHEFS specifically for international professional chefs.
